How it works

  • Converted estimate = × Conversion factor
  • Roman foot (pes) ≈ 0.296 m; Roman digit = Roman foot (pes)/16; Roman palm = Roman foot (pes)/4
  • Roman cubit = 1.5 × Roman foot (pes); Roman pace (passus) = 5 × Roman foot (pes); Roman mile = 5,000 × Roman foot (pes)
  • Worked example: With the selected 296 mm Roman foot profile, one Roman mile is 5,000 feet. The result is a historical estimate, not the modern international mile.
  • 5,000 × 0.296 ≈ 1,480 m.

Assumptions and limitations

Approximate historical reference. SI arithmetic does not make reconstructed ancient dimensions exact; use the named profile and its sources.
